[Glade-users] Button only receiving input after leaving & re-entering button



Hi,

I am running Gtk 2.12.9 ... reading the bug you linked to, it seems
that this was fixed in 2.14, so this should be fixed in newer
versions. It's a bit annoying but I'm glad that it's not my code which
is causing this :-)

Greetings/Thanks
Robert

Hi,

I have a window which contains a button created through the custom
function below:

GtkWidget*
create_randomize (gchar *widget_name, gchar *string1, gchar *string2,
? ? ? ? ? ? ? ?gint int1, gint int2)
{
?GtkWidget *button;
?GtkWidget *hbox;
?GtkWidget *label;
?GtkWidget *die;

?button = gtk_button_new ();
?hbox = gtk_hbox_new (FALSE, 0);
?die = create_pixmap (button, DATA_DIR "/glade/die.xpm");
?label = gtk_label_new (_("Roll Again"));
?gtk_box_pack_start (GTK_BOX (hbox), die, FALSE, FALSE, 0);
?gtk_box_pack_start (GTK_BOX (hbox), label, FALSE, FALSE, 0);
?gtk_container_add (GTK_CONTAINER (button), hbox);
?gtk_widget_show_all (button);

?gtk_signal_connect (GTK_OBJECT (button), "clicked",
? ? ? ? ? ? ? ? ? ? ?(GtkSignalFunc) on_randomize_clicked,
? ? ? ? ? ? ? ? ? ? ?NULL);
?gtk_widget_show_all (button);
?return button;
}


The code handling a click on this button looks like this:

?void
on_randomize_clicked ? ? ? ? ? ? ? ? ? (GtkButton ? ? ? *button,
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?gpointer ? ? ? ? user_data)
{
?MainState *main_state;
?GtkWidget *chooser_window;
?GtkWidget *main_window;
?gint ? ? ? i;
?int ? ? ? ?types;
?char *widgets[] = {
? ?"t1", "tt2", "t3", "t4", "tt5", "t6", "t7", "t8", "tt9", NULL };

?chooser_window = lookup_toplevel (GTK_WIDGET (button));
?main_window = lookup_data (chooser_window, "data_parent");
?main_state = lookup_data (main_window, "data_state");

?gtk_object_ref (GTK_OBJECT (chooser_window));
?gtk_widget_set_sensitive (GTK_WIDGET (button), FALSE);

?/* make sure the type bitmap holds a valid value */
?if (user_data != NULL)
? ?types = *((int*)user_data);
?else
? ?types = 0;

?for (i = 0; widgets[i] != NULL; i++)
? ?{
? ? ?TTerrain ?*terrain;
? ? ?GtkWidget *widget;
? ? ?GtkWidget *view;

? ? ?while (gtk_events_pending ())
? ? ? ?gtk_main_iteration ();

? ? ?/* Break out of loop if window is closed. */
? ? ?if (!GTK_WIDGET_REALIZED (chooser_window))
? ? ? ?break;

? ? ?widget = lookup_widget (GTK_WIDGET (button), widgets[i]);
? ? ?view = gtk_object_get_data (GTK_OBJECT (widget), "view");

? ? ?terrain = t_terrain_generate_random (main_state->default_size,
main_state->genfactor, main_state->gentypes);
? ? ?t_terrain_view_set_terrain (T_TERRAIN_VIEW (view), terrain);
? ?}

?gtk_widget_set_sensitive (GTK_WIDGET (button), TRUE);
?gtk_object_unref (GTK_OBJECT (chooser_window));
}


This works but the problem is that when the randomization process
finishes and the mouse is still on the randomize button, the randomize
button seems active (ie: it is not grayed out) but clicking on the
button does not result in any actions. When I move the mouse out of
the button and then again into the button, then clicks are once again
received and properly processed. It seems that I am not setting some
state correctly, but I don't know what I would have to do in order to
fix this.

Any ideas would be much appreciated.

Greetings/Thanks
Robert
